4 Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. ISO was prepared by Technical Committee ISO/TC 23, Tractors and machinery for agriculture and forestry, Subcommittee SC 19, Agricultural electronics. This second edition cancels and replaces the first edition (ISO :2007), of which it constitutes a minor revision. ISO consists of the following parts, under the general title Tractors and machinery for agriculture and forestry Serial control and communications data network: Part 1: General standard for mobile data communication Part 2: Physical layer Part 3: Data link layer Part 4: Network layer Part 5: Network management Part 6: Virtual terminal Part 7: Implement messages application layer Part 8: Power train messages Part 9: Tractor ECU Part 10: Task controller and management information system data interchange Part 11: Mobile data element dictionary Part 12: Diagnostics services Part 13: File server Part 14: Sequence control iv ISO 2011 All rights reserved

5 Introduction Parts 1 to 14 of ISO specify a communications system for agricultural equipment based on ISO [1] and ISO [2]. SAE J1939 [3] documents, on which parts of ISO are based, were developed jointly for use in truck and bus applications and for construction and agriculture applications. Joint documents were completed to allow electronic units that meet the truck and bus SAE J1939 specifications to be used by agricultural and forestry equipment with minimal changes. General information on ISO is to be found in ISO The purpose of ISO is to provide an open, interconnected system for on-board electronic systems. It is intended to enable electronic control units (ECUs) to communicate with each other, providing a standardized system. The International Organization for Standardization (ISO) draws attention to the fact that it is claimed that compliance with this part of ISO may involve the use of a patent concerning the controller area network (CAN) protocol referred to throughout the document. ISO takes no position concerning the evidence, validity and scope of this patent. The holder of this patent has assured ISO that he is willing to negotiate licences under reasonable and nondiscriminatory terms and conditions with applicants throughout the world. In this respect, the statement of the holder of this patent right is registered with ISO. Information may be obtained from: Robert Bosch GmbH Wernerstrasse 51 Postfach D Stuttgart-Feuerbach Germany Attention is drawn to the possibility that some of the elements of this part of ISO may be the subject of patent rights other than those identified above. ISO shall not be held responsible for identifying any or all such patent rights. ISO 2011 All rights reserved v

7 INTERNATIONAL STANDARD ISO :2011(E) Tractors and machinery for agriculture and forestry Serial control and communications data network Part 13: File server 1 Scope ISO as a whole specifies a serial data network for control and communications on forestry or agricultural tractors and mounted, semi-mounted, towed or self-propelled implements. Its purpose is to standardize the method and format of transfer of data between sensors, actuators, control elements and information storage and display units, whether mounted on, or part of, the tractor or implement. This part of ISO specifies the file server (FS) for use by a tractor or self-propelled implement. 2 Normative references The following referenced documents are indispensable for the application of this document.
